Are there any activities you can do in the game with your friends/allies besides battling an enemy together? You know such as quests, maybe some other stuff... It would be fun to interact with your friends in some ways and work together for something often. Because big battles won't happen as often, maybe once a week or so... I mean it takes time to rebuild, etc. And you really have to prepare for them.
So yeah, in between those, what is there to occupy yourself with?

A week to get into battle? once your in the game with your stronghold and your a higher level, it wont take a real human "week" to get into battle with larger armies or rebuild after being defeated. The game has its own time, day night cycle, weather system and seasons. 10080 real seconds is 1 in game week, which is 168 real minutes, which is 2.8 real hours.

Co-op quests with your friends sounds very good in my ears, other than that I won't comment.

I really hope there will be co op quests...if not then I hope you add them later... I mean that would be so fun to do.
Wait, 2.8 hours?! That means night and days will pass in minutes! I mean I won't have time to enjoy the sights of day and night, and for example I'm a day person so I usually like to play online games when it's day, or at least it lasts more, but this way they'll keep going back and forth really fast...but oh well.

If 1 in game week is 2.8 real hours, then a building what takes to construct 2 weaks, will be ready after 5.6 real hours, but some manage to play 3 hours a day, then the construction will be ready in the online time or it will construct in offline mode to ?
